Problems solved by technology

Through literature research, so far, 5 kinds of glycosides and β-sitosterol have been isolated from plants of the genus, but the chemical components of the green bark of macadamia nuts from the same family of Longan plants have not been reported, and the green bark may contain a large number of active substances. Substances have not been rationally developed and utilized. Therefore, the rational development and comprehensive utilization of macadamia nuts produced in Yunnan is an important issue for the nut industry to extend the industrial chain, comprehensively utilize resources, and increase the added value of macadamia nuts.

[0045] 3. Preparation of macadamia nut green bark extract

[0046] The above experimental results show that when the macadamia nut green skin is extracted with 75% to 95% ethanol under reflux, the content of tofu fruit glycosides is higher when extracted with 95% ethanol, but the alcohol extract is light green, and the pigment needs to be removed. Considering the green skin The lotion should be water-soluble, so for the ethanol extract of Qingpi, dissolve it with ultra-pure water, filter it, remove water-insoluble impurities, use petroleum ether to degrease, remove part of the pigment, and the water layer still has pigment that has not been removed, use activated carbon to decolorize method, depigmentation, and concentration of the water layer under reduced pressure to obtain macadamia nut green bark extract. specifically is:

Embodiment 1

[0048] (1) Take the fresh macadamia nut green skin and dry it in the shade, remove the impurities attached to the surface, crush the green skin to a diameter of less than 1.0cm, add 20 times the amount of 75% ethanol, and reflux extraction for 3 times, each time for 1 hour, at a reflux temperature of 60°C, and merge three times The filtrate was filtered with suction to obtain the green alcoholic extract of Qingpi;

[0049] (2) The alcohol extract is concentrated under reduced pressure until the ethanol is completely volatilized to obtain the crude extract of Qingpi;

[0050] (3) Add the crude extract to ultrapure water until completely dissolved, extract and degrease with petroleum ether at 30°C, the ratio of petroleum ether to the aqueous extract solution is 1:1, after extraction 3 times, add activated carbon to the remaining aqueous solution and stir for 60 minutes Obtain the aqueous solution of green bark that removes chlorophyll, and above gac and remaining aqueous solutio...

Embodiment 2

[0053] (1) Take the fresh macadamia nut green skin and dry it in the shade, remove the impurities attached to the surface, crush the green skin to a diameter of less than 1.0cm, add 20 times the amount of 80% ethanol, and reflux extraction for 3 times, each time for 1 hour, at a reflux temperature of 60°C, and merge three times The filtrate was filtered with suction to obtain the green alcoholic extract of Qingpi;

[0054] (2) The alcohol extract is concentrated under reduced pressure until the ethanol is completely volatilized to obtain the crude extract of Qingpi;

[0055] (3) Add the crude extract to ultrapure water until completely dissolved, extract and degrease with petroleum ether at 60°C, the ratio of petroleum ether to the aqueous extract solution is 1:1, after extraction 3 times, add activated carbon to the remaining aqueous solution and stir for 45 minutes Obtain the green skin aqueous solution that removes chlorophyll, and above gac and remaining aqueous solution w...

Abstract

The invention discloses a method for preparing macadimia nut green-peel extractum and lotion, and belongs to preparation of plant extract and lotion. The method comprises the steps of: crushing fresh macadimia nut green peel and leaching effective components by an ethanol solvent after rinsing, carrying out rotary evaporation concentration until the extractum with a required concentration is obtained after being degreased by petroleum ether, and then preparing macadimia nut green-peel lotion by using humectants, bacteriostatic agent, essence, deionized water and the like according to a commonmethod. The lotion disclosed by the invention contains effective components of arbutin, hilicid and the like; the physical state of the lotion forms translucent gelatinous liquid; the color and the luster are little faint yellow; the lotion has good sleeping and moisturizing actions, and a way is provided for resource utilization of the macadimia nut green peel.

Description

technical field [0001] The invention belongs to the preparation of plant extracts and lotion, in particular to the preparation of macadamia nut green bark extract and the lotion produced by using the extract as raw material. Background technique [0002] Macadamia Macadamia ternifolia F.Muell is Proteaceae (Proteaceae), Macadamia genus ( Macadamia) , an evergreen tree, a dicotyledon, native to the subtropical rainforests of Queensland and New South Wales, Australia. Macadamia nut kernels have a unique flavor and rich nutritional content. They are one of the four famous nuts in the world. In Europe and America, they are considered to be one of the best table nuts in the world. [0003] Macadamia nuts were introduced to China in the 1960s and 1970s. In recent years, a preliminary industry has formed in Yunnan Province of my country, especially after the introduction and cultivation in Dehong Prefecture, it has been planted on a large scale and will gradually become the m...
